Abstract

Provided is a laminated iron core (10), in which the connecting portions (12) of an outer circumference region (11) for connecting adjoining segment iron cores (13) are folded, in which the continuous segment iron cores (13) are spirally wound and laminated while being adjusted at their end portions, and in which the connecting portions (12) for the adjoining layers are arranged while being deviated in the circumferential direction. On the radially outer sides of the connecting portions (12), the laminated iron core (10) includes recessed notches (22) for housing radially bulging portions (21) formed on the radially outer side at the time of folding the connecting portions (12), within the outer circle of the laminated iron core (10). On the radially inner sides of the connecting portions (12), inside notches (23) for forming the folding positions of the connecting portions (12) are provided. On the radially outer sides of the segment iron cores (13) excepting the connecting portions (12), housing recesses (16 , 17) of bulging portions (15), which are formed in thickness direction thereof fronts and backs of the connecting portions (12) when these connecting portions (12) are folded, are provided at front and rear sides thereof.
